我有一个应用内结算服务，其中有两个消耗品和一个非消耗品。
对于非消耗品，我正在检查购买清单，如果该物品已经拥有，我希望用户不再购买，而是提供优惠。我有两个类：Guess.java（Launcher文件）和Purchase.java（应用内结算设置文件）
Guess.java内部
Intent intent = new Intent(Guess.this,Purchase.class);
intent.putExtra("buy_2x", "buy_2x");
startActivity(intent);
buy_2x是非消耗品（购买选择在下面的代码中是2，而消费品是购买选择0和1的消费品），我指的是。在Purchase.java中，代码如下
public class Purchase extends Activity {
IInAppBillingService mService;
private Bundle extras;
private int add=0;//add coins to the kitty
private int buying_choice;
private String ITEM_SKU_SELECTION;
private static final String TAG = "com.apps.guess.inappbilling";
IabHelper mHelper;
private ServiceConnection mServiceConn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String base64EncodedPublicKey = "<64-char> long";
Intent intent = getIntent();
String buy2x_recd =intent.getExtras().getString("buy_2x");
//this is a class that contains static variables and I am using choices
//0,1,2...choice 2 is for the non-consumable buy_2x
if(UserData.getBuying_choice()!=2) ITEM_SKU_SELECTION = selectbuyingChoice(UserData.getBuying_choice());
//callService() method referred below
if(buy2x_recd.equalsIgnoreCase("buy_2x"))callService();
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.startSetup(new
IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result)
{
if (!result.isSuccess()) {
Toast.makeText(getApplicationContext(), "In-app Billing setup failed: = ", Toast.LENGTH_LONG).show();
Log.d(TAG, "In-app Billing setup failed: ");
} else {
Log.d(TAG, "In-app Billing is set up OK");
mHelper.launchPurchaseFlow(Purchase.this, ITEM_SKU_SELECTION, 10001,mPurchaseFinishedListener, "");
mHelper.enableDebugLogging(true, TAG);
}
}
});
}//onCreate() ends
public void callService(){
mServiceConn = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name,
IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
Log.d("TEST", "mService ready to go!");
checkownedItems();
}
@Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}
};
bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);
}
private void checkownedItems()
{
try {
Bundle ownedItems = mService.getPurchases(3, getPackageName(), "inapp", null);
int response = ownedItems.getInt("RESPONSE_CODE");
if (response == 0) {
ArrayList<String> ownedSkus =
ownedItems.getStringArrayList("INAPP_PURCHASE_ITEM_LIST");

String continuationToken =
ownedItems.getString("INAPP_CONTINUATION_TOKEN");
for (int i = 0; i < purchaseDataList.size(); ++i) {
String purchaseData = purchaseDataList.get(i);
String signature = signatureList.get(i);
String sku = ownedSkus.get(i);
if(sku.equalsIgnoreCase("buy_2x"))
{

builder.setTitle("Purchased Already");
builder.setMessage("You have already purchased the 2X option. Do you want to enable it?");

我收到以下警告：
Implicit intents with startService are not safe: Intent { act=com.android.vending.billing.InAppBillingService.BIND } android.content.ContextWrapper.bindService:517 Purchase.callService:107 Purchase.onCreate:68
错误如下：
IabHelper(25782): In-app billing error: Unable to buy item, Error response: 5:Developer Error
UserData.java存储一些值并写入数据文本文件。他们没有问题。
这是什么问题？请帮忙。谢谢

您是否尝试使用GooglePlay开发者帐户购买设备上记录的商品？
谷歌不允许这样做。你应该使用另一个。
在开发者控制台中，转到“帐户设置”并添加一些帐户进行测试。然后，使用其中一个登录，尝试购买该项目。你应该能够实现它。
编辑：
检查文档，我发现您必须使用有效签名的apk http://developer.android.com/google/play/billing/billing_reference.html进行测试

您只需要在清单上给PAY_THROUGH _...（您在其中应用的evrey商店）： 例如，cafebazar商店： 或用于Play商店：...。
